ESPADD.BR: Expert System Producing Automated Designs and Drawings for Bridges
This paper presents the logic and methodology used in developing an automated software system for designs and drawings of bridges. Its primary purpose is to design and draw highway bridge...
Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....
Automated Design of 3-D Highway Sign Bridge Structures
A PC-based computer analysis/design program for 3-D Sign Bridge Structures including Pre- and Post-processor has been developed. The analysis of thirty different types of sign support...
How do Integration and Data Models Add Value to a Project?
Integration has been at the forefront of research agendas of universities and restructuring efforts of companies in the past few years. However, we are still lacking a common understanding...
Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...
Flexible Extracation of Practical Knowledge from Bridge Databases
Bridge databases contain significant information that can assist in future bridge management decisions. The effective utilization of this information requires facilities for the flexible...
Performance of New York's Long-span Bridges
This paper is a work-in-progress report on a database on the performance of long-span bridges located in New York State and built between 1801 and 1993. Of the 68 long-span bridges - bridges...
Modeling Initial Mixing of Ocean Wastewater Discharges to Develop Toxic Effluent Limitations
The UM model, released by USEPA in 1992, was utilized to simulate the initial mixing of a discharge to the Atlantic Ocean near Ocean City, New Jersey. The study included field verification...
Adaptive Instructor Model for an Engineering ITS
To develop intelligent tutoring systems (ITS) for engineering via computer technology, a model of how engineers learn as well as methods in which instruction should occur must be captured...
Microworlds for Learning Through Inquiry
We discuss several computer-based environments to support learning through inquiry, called microworlds, including two focused on steam power plant operation and electronic troubleshooting....
Empirical Performance Comparison for Symbolic and Subsymbolic Learning Systems
The paper gives a description of a comparative study of two learning systems based on symbolic and subsymbolic learning. The two systems' performance was analyzed using the overall empirical...
An Inductive Knowledge-Based System for Mitigation of Bridge Fabrication Errors
Fabrication and erection of steel bridges are very error-prone processes. Bridge engineers at the Kansas Department of Transportation (KDOT) felt that there is a need for the development...
Seismic Evaluation of the Macy Street Bridge, Los Angeles, California, Using 3-D Nonlinear Pushover Methodologies
Nonlinearity of the overall bridge response has begun to be incorporated in the design process through a method known as nonlinear static pushover analysis, and this step is now being...
Nonlinear Analysis and Experimental Validation of a Stiffening Truss Chord of the Golden Gate Bridge
Finite element analyses of a stiffening truss chord of the Golden Gate Bridge were conducted by the authors as part of a comprehensive seismic retrofit project conducted by T. Y. Lin International...
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
A Knowledge-Intensive Database System for Making Effective Use of Construction Lessons Learned
The Constructability Task Force of the construction Industry Institute (CII) sponsored as series of studies which advocate construction expert input to the conceptual planning, engineering...
Creating and Abstracting Lessons-Learned from BCO Reviews
This database allows reviewers searching for relevant past expertise access to a relatively small set of comments that have been retained frequently for past reviews. The ability to order...
Three-dimensional Modeling for Improving Construction Process Performance
